Plants naturally get a high dose of red light in the evening as the sun sets. According to research from Sweden I think, plants grown indoors which do not get a large dose of red light before sleep fall asleep confused, and therefore take 3-4 hours to fall asleep completely. Here's the neat thing: by blasting plants with 10-15 minutes of red light from your chosen source (red LED's or bulbs around 3000k from what I know), these scientists found plants go to sleep instantly! And when plants go to sleep right away and get a good nights rest, they also wake up instantly it turns out. When plants fall asleep confused, it takes them a long time to wake up, sometimes several hours. I notice the leaves on my plants begin to droop within 15 minutes of being hit with warm light before their bed time (I also turn off my main LEDs during this time). I used to do 30 minutes but Harley Smith and these Swedish researchers recommend just 10-15 minutes as enough time. I highly recommend this neat growing technique, you will notice your plants falling asleep and waking up faster! Update 10/26/2018: Did some research and need to include some specifics for this to work. I also found a confound in my little experiment, it turns out my plants leaves "drooping within 15 minutes" is most likely from me turning off my main LED light, not the red light across the room. Okay so here is the clarification: plants need INFARED light, not red light, to trigger that instantaneous sleep cycle. My light bulbs (3000k) are definitely not producing the right light to trigger this response. Like I said, my plant leaves drooping were drooping from the main LED being turned off at the same time. My lightbulbs at most have been providing extra yellow light basically, like they appear to the eye (3000K makes for 600 nm). Interestingly, if anyone would like to know, infared light is produced by the human body. There is a chance that body heat helps plants sleep if you sort of tuck them into bed before sleep by hanging out with them just before they go to sleep. Candle flames also provide far red light and so probably trigger the rapid sleep cycle. HID lights also give off infared light because infared light is essentially nearby heat. Maybe we should all be lighting up and hanging out with our plants just before their bed time to help them sleep better! Just kidding, but I wonder if these things work as a trigger for sleep!
I think everyone should start a post when they start a new grow... After all, every grow is an experiment unless you have some very expensive control factors to em like perfect cloning and environmental control!! So I cleared a grow w/ the roomie. The setup: The same as always of course guys c'mon, a 3x3 tent, 200 cfm squirrel fan w/ carbon filter inside, the same 2 little fans, and all holes in tent covered by carbon filters. Room temperature, usually 40-60% rH indoors. I was thinking about doing just one plant this time. Usually I do multiple plants because as a newer grower I may fail with one plant and succeed with another, which worked well for me. But with some more experience with growing indoor plants in general and the exotic marijuana plant, I was considering doing just 1 and trying to get a bigger yield. I may do 2 plants. I have many seeds to choose from so I wasn't considering getting a clone. I have random outdoor seeds from my friends that I love their outdoor (unnamed seeds), and many seeds from random clubs over the years. The freshest are the unnamed seeds and the others are anywhere from less than a year to a couple years old or so. I have the following strains and would take advice if anyone has any! : cannatonic, kosher kush, blue cookies, pre-98 bubba, mendo purple glue, crumpets, and platinum OG. And of course my buddies random outdoor strains. I was also considering autoflowers if I can find the genetics somehow. I've heard of really good things. I could maybe get a fast succession going cloning them going if I can make a small veg room as well. They complete their cycles very quickly so that could be a neat succession. Any opinions?
